SHAFT-HANGER SUPPORT.

Specification of Letters Patent. A

t p e Patented May as, 1911.

Application filed August 27, 1909. Serildlll'dml To all whom fit mayconcern:

Be it known that I,l JULnTs KAI-IN, a citizen of the United States, anda resident of v Detroit, in the county of Wayne and State of Michigan,have invented a new `and lmroved Shaft-Hanger Support, of which theollowing is a specification.

This invention relates to meansl adapted to be embedded in the lowersides of beams, floors, ceilings and other structures of concrete tofurnish connections to su port shaft hangers and other machinery, an(vthe object of .my improvement is to provide a hanger which shall besimple in construction, easily assembled, and of great strength.

In the accompanying drawings, Figure 1 is a perspective view of thisimproved shaft han er support. Fig. Qiis an inverted plan of t e same.Fig. 3 is 'a cross section on the line 3-3 of Flg. 4. Fig. 4 is a crossseetion on the line 4.-4 of Fig. 3.

Similar reference characters refer to like parts throughout the severalviews.

The increased use of'reinforced concrete has introduced the same into`factory construction where floors and beams are made of this materialto a large extent. As the material becomes extremely hard, it is verydifficult to drill holes through the same for bolts to supportshaft-hangers and other machinery. Means to permit the ready attachingand detaching, of/ machinery are therefore embedded ili/ the concretefloors and girders before/the concrete has hardened, and the drawingsshow an improved device for such purpose.

The two parallel, rolled-steel channels 1 have inturned flanges 2 and 3.Bolts 4 have any desired enlargements 5 at their upper ends and arethreaded at their lower ends to receive the Vnuts 6 and 7. 'llie nut 7may lloe formed to fit the inner faces of the flanges 2 of thech..unels. Extendingv over the upper faces of the channels, and shortdistances down the sides if desired, are the plates 10 which hold thechannels positioned and also prevent the concrete from filling the spacebetween the channels.

The supports are assembled by placing the plates l() over a pair ofchannels, screwing the'v nuts (l up onto the bolts and then screwingthe'boltsinto the nuts 7, heldin proper position. The nuts 6` are thenscrewed down to lock the parts together. The finished supports can bemade of any length, and the dimensions of the angles and the sizes andspacing of the bolts 4 will depend upon the load to be carried.

The finished hangers are properly placed on the false-work and concrete11 is molded around them in the usual manner. The lower flanges 3 of thechannels are provided with notches 12, where necessary, to permit theintroduction of theflheads 13 of the hanger bolts 14, which securehangers 15 of other machinery in position. The concrete, afterhardening, will prevent the channels from spreading so the plates 10need be of but thin metal. As the parts can readily be assembled theycan be slipped in bundles and thus avoid damage.

llavinlr now` explained my improvements what I clairnf as my inventionand desire to secure bylLetters ,lfatcnt is:-

1. A shaftmhailiger support comprising cha nnel bars having inturnedflanges, plates extending along above the channel bars and havingtheir.edges` turned down to hold the channel hars parallel to` eachother, bolts extending upward from between the channel hars. nutsl onthe bolts above and below the upper flanges of the channel bars to holdthe parts in position and means carried by the channel bars 'forsupporting a shaft hanger. v

2. A machinery support, consisting of an insert for concreteconstruction, comprising channels disposed parallel to each other withtheir flanges extending toward each other, bolts extending upward 'frombetween the channels. nuts on the bolts above and below the upperflanges on the channels and gripping the same to hold the channels inposition, and supporting means carried by the channels; y

In testimony whereofl have signed 'this specification in the pre-'enceof two subscrib-
